For somme reason the people involved either got no vaccination (required to get into school now) or got a bad batch.
Hmmm, what group of ppl would not have had the shots mandatory in the USA?
I live in Iowa and at least in this area of the state there are more kids in christian schools(netherland reformed mostly)and it is bypassed because of their religion.
Or perhaps are carrying a strain the current vaccine doesn't protect against?
Anyone with allergies or severe asthma. My son (b.1965) has congenital asthma diagnosed as adrenal insufficiency (in some sort of remission since he has been about 35, thank God!), As I recall, at that time, at least, the vaccine was produced in horse serum and the MD said he could not have it. He had a waiver on his medical record. Funny thing is, we tried to expose him so he would have primary immunity, as we both have, being born prior to the vaccine. He never caught it. Except for the asthma, he has always had wonderful health and has great teeth, too.
Good question. What people would not have had the vaccination required in the states? HMMMMMMMMMMMMM? This is for the politically correct crowd that won't call the shots as they are. To them you can only say - DUH?????????????
